Check Belt/V-Belt Adjustment; Change Engine Oil; Checking Tire Pressure; Checking Battery - Craftsman 917.253724 Owner's Manual

FIRST HOURS
1_ CHECK BELT ADJUSTMENT
New Belts may stretch after the first few hours of operation
resulting in loss of power.
am With engine running, transmission in neutral, place Vari-
drive Control Lever in "FAST" position (Fig. 11) and
check if Secondary Belt (Fig. 16 - Inset) rides flush with
outside of Variator Sheave (DO NOT PUSH DOWN ON
CLUTCH PEDAL).
b, If Secondary Belt is riding down in groove of Variator
Sheave adjustment is required,
2. V-BELT ADJUSTMENT
a With engine running, Transmission in "NEUTRAL"
position, move Varidrive Control Lever to full "FAST"
position (Fig. 11)
b. Shut engine off and loosen Adjustment Nut on Bolt "A"
for Variator Stop Plate (Fig. 16).
c, Start engine and run at idle Speed
d Slowly move Vafidrive Control Lever (Fig. 11) forward
or backward until Secondary Belt is riding flush to
1/16" outside of Variator Sheave (Fig 16 - Inset).
NOTE: DO NOT PUSH DOWN ON CLUTCH PEDAL.
e., Shut engine off holding Varidrive Control Lever in posi-
tion as described in step d and tighten Adjustment Nut
on Bolt "A" (Fig. 16).,
f, Start engine and move Varidrive Control Lever to
SLOW posttlon (F_g. 11). Primary Belt should ride
flush to 1/16" out of Variator Sheave (Fig. 16 - Inset).
g Adjustment is complete when the Secondary Belt rides
in the same position on the Variator Sheave in full
"FAST" position, as the Primary Belt does in the
"SLOW" position,
h Re-adjust as needed thereafter
i f Be t cannot be adjusted as described in step g replace
V-Betts= Refer to Belt Replacement , page 12.
3. CHANGE ENGINE OIL
Changing Oil after the first two hours will help eliminate
break4n residue which might be damaging to your Engine,
NOTE: BE CAREFUL NOT TO ALLOW DIRT TO ENTER
THE ENGINE WHEN CHANGING OIL.
a Drain Oil with Engine warm, Unscrew Oil Drain Plug
(Fig. 18) and catch Oil in a suitable container, Replace
Plug,
b Refill Engine Oil (Fig° 17). In summer use S.AE. 30
(SC, SD, SE or SF) Oil. in winter (below 32°F) use
S,A.E_ 10W30 (SC, SD, SE or SF). In extreme cold
(below 0°F.) use S.A_E 5W20 (SC, SD, SE or SF). DO
NOT USE 10W40 OIL. Refill capacity is 3 pints_ NOTE:
DO NOT OVERFILL,
FREGUENTLY
1_ CHECK BATTERY
a Electrolyte solutlon teve] in each Battery Ceil should be
even with bottoms of tubes in cells (Fig. 19)o Add dis-
tilled water if necessary NOTE: DO NOT OVERFILL
b, Keep Battery and Terminals clean, Refer to page !2,
step 6.
co Keep Battery Bolts tight.
d. Keep Vent Caps tight and small vent holes in Caps open.
e_ Recharge SLOWLY at 3 amperes if necessary.
2, CHECK TIRE PRESSURE
Tire pressure in front should be t4 pounds and rear Tires
should be 10 pounds_
3, CLEAN AIR SCREEN
Air Screen (Fig,, 17) must be kept free of dirt and chaff to
prevent Engine damage from overheating.,
